BRATTLEBORO — In the Green Mountain State, Vermonters’ love for the outdoors and passion for local brews have come together in a state-brewery collaboration.

Vermont State Parks and Whetstone Station in Brattleboro have brewed up a partnership that features two state park-named beers, Fort Dummer Summer and Molly Stark Dark, brewed with water sourced directly from those two state parks, a press release from the state parks stated.

The partnership also includes free entry to state parks and local charitable giving.

Beginning Wednesday, Whetstone will give away up to 100 vouchers for free park entry into Fort Dummer and Molly Stark state parks to patrons who order these limited edition brews. Fort Dummer and Molly Stark parks will also distribute vouchers for a complimentary koozie at Whetstone Pub & Brewery.

A press release also provided the following information about the brews:

Fort Dummer Summer, Release date: Wednesday

“This beer is a tribute to the beautiful Fort Dummer in Guilford. Bright, fresh and clean, this brew combines local malt, traditional hops and fresh water collected from the Broad Brook, located in Fort Dummer State Park and brings it all together in this delicious way to celebrate the season. At just 5 percent alcohol by volume, this session pale ale is a perfect brew to enjoy in the sun. Extremely limited and available draft only, this tasty summer beer won’t be around long. You can also find Fort Dummer Summer at the sold-out Vermont Brewers Festival July 18-19,” the release stated.

Molly Stark Dark, Release date: Aug. 13

“This beer is a tribute to the Vermont State Park of the Year, Molly Stark State Park in Wilmington. This American take on a Dunkelweizen combines Massachusetts grains, fresh water collected from within the park itself, a Vermont yeast strain and a touch of local hops, into a dark, but light, sweet and delicious beer. Follow the Molly Stark trail to Brattleboro and enjoy this draft-only, extremely limited, craft beer while it lasts. At just 4 percent alcohol by volume, it’s full of flavor.

The launch dates of each brew are set for Whetstone’s Community Pint Nights. Each Wednesday, $1 from every brew sold goes to a local charity.
